如何排除“。”与.dir文件文件夹中的scandir? [重复]

问题描述 投票:-1回答:1

我有一个包含几个名为.txt的文件的文件夹:

A500_1.txt
A500_2.txt
A700_1.txt
A700_2.txt
A900_1.txt
...

在每个.txt文件中都有:

PRXC1_|TB|CCAAO9-RC|9353970324463|24.99
PRXC1_|TB|CFEXK4-RC|9353970294766|84.99
PRXC1_|TB|CFEXK4-RC|9353970294773|84.99

...

我希望你:

  • 如果文件名以A500_开头,则将“ TB”替换为“ MD”

  • 如果文件名以A700开头,请用“ JB”替换“ TB”

  • 如果文件名发送者代码在此处用A900_替换,则将“ TB”替换为“ LD”

我已经完成了此功能,但是当我执行它时,我的错误是这样的:

Warning: file_get_contents(.): failed to open stream: Permission denied in C...

我认为这是从我的scandir显示“。”和“ ..”

如何只读取文件夹中的.txt文件并替换文件中的字符?

<?php
function processFile( $path ) {

   $dir    = './test/';
   $allFiles = scandir($dir);

   foreach($allFiles as $file) {

       $filename = basename( $file );

       //read the entire string
       $str = file_get_contents( $file );
       echo $file;

       // replace something in the file string
       if ( strpos( $filename, 'A500_' ) === 0 ) {
           $str = str_replace( 'TB', 'MD', $str );
       } else if ( strpos( $filename, 'A700_' ) === 0 ) {
           $str = str_replace( 'TB', 'JB', $str );
       } else if ( strpos( $filename, 'A900_' ) === 0 ) {
           $str = str_replace( 'TB', 'LD', $str );
       } else {
           // Return false if we don't know what to do with this file
           return false;
       }

       //write the entire string    
       $writeResult = file_put_contents( $file, $str );
       //return true after a file is written successfully, or false on failure
       return $writeResult >= 0;
  }
}

if(processFile( './test/' )) echo "good!";
?>
php scandir
